4 Subject: [PATCH] arm64: dts: rockchip: Add rk3566 based Radxa Compute Module 3
5 MIME-Version: 1.0
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit
8
9 Radxa Compute Module 3(CM3) is one of the modules from a series
10 System On Module based on the Radxa ROCK 3 series and is compatible
11 with Raspberry Pi CM4 pinout and form factor.
12
13 Specification:
14 - Rockchip RK3566
15 - up to 8GB LPDDR4
16 - up to 128GB high performance eMMC
17 - Optional wireless LAN, 2.4GHz and 5.0GHz IEEE 802.11b/g/n/ac wireless,
18 BT 5.0, BLE with onboard and external antenna.
19 - Gigabit Ethernet PHY
20
21 Radxa CM3 needs to mount on top of this IO board in order to create
22 complete Radxa CM3 IO board platform.
23
24 Since Radxa CM3 is compatible with Raspberry Pi CM4 pinout so it is
25 possible to mount Radxa CM3 on top of the Rasberry Pi CM4 IO board.
26
27 Add support for Radxa CM3.
